Interior Roof Accessories

Ceiling

The metal ceiling system consists of 3" deep 16" wide interlocking panels of nominal 24 gauge embossed galvanized steel, factory painted Arctic White. The ceiling system is supported at its perimeter by concealed angles and hook bolts. The ceiling system is furnished complete with all necessary connectors and fasteners.

Options:

• The ceiling can be insulated with 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation laid at right angles to the panel ribs. The "U" value through the finished ceiling would be a maximum of 0.09 BTU's per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition. Eave height -6".
• The ceiling can be insulated with 2 layers of 16" wide by 3-1/2" thick R13 unfaced fiberglass insulation 1st layer laid in panel void, 2nd laid at right angles to the panel ribs. The "U" value through the finished ceiling would be a maximum of 0.06 BTU's per square foot (R15.9) when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition. Eave height -6".
• The ceiling can be insulated with 2 layers of 16" wide by 3 1/2" thick R-13 unfaced fiberglass insulation laid at right angles to the panel fibs. The "U" value through the finished ceiling would be a maximum of 0.05 BTU's per square foot (R21.3) when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition. Eave height -9".
• Ceiling panels can have acoustical perforations across 14" of the panel width. Perforations would be 1/8" diameter on a patterned spacing of 3/8". The acoustical ceiling system has been certified by an independent testing laboratory for a minimum NRC rating of 0.95 when tested in accordance with ASTM C423 standards.

Roof Insulation

Roof insulation consists of 48" wide, 3" thick, .6# density fiberglass faced on its exposed side with a white metalized polyproplene scrimkraft facing. The faced insulation material has a UL Flame Spread Rating of 25 when tested in accordance with UL 723 or ASTM E-84 procedures.

Insulation is supported at the roof line by means of mechanical clips spaced on maximum 4' centers and is sealed by means of a 2" side tabs on the facing. The "U" value through the insulated roof is a maximum of 0.10 BTU's per square foot when calculated in accordance with the "Zone Method" contained in ASHRAE "Handbook of Fundamentals", 1981 edition.

3" Therma-Roof

Roof insulation consists of 48" wide x 8' and 12' long polyisocyanurate foam board faced with a white embossed coated foil on the exposed interior surface.

Insulation has a maximum UL Flame Spread Rating of 25, fuel contributed rating of 10 and Smoke Developed Rating of 155-190 when tested in accordance with UL723 testing methods and meets the requirements of the Underwriters Laboratories "Wall-Ceiling" Construction Classification.

The roof insulation system includes metal supporting tees on 4' centers and all trim required for a finished interior appearance.

Insulation thickness is 3", R9.1, R Value is calculated by the "Zone" method contained in ASHRAE Handbook of Fundamentals" 1981 edition.
